This study was carried out to investigate the effects of climatic conditions on the budding of buds and the growth of shoots of mulberry (Morus alba L.) at Suwon for the period of six years from 1978 to 1983. The results are summarized as follows. 1. The period that influenced most greatly on mulberry budding and foliating of it's buds was from late part of March to middle part of April in the district of Suwon, Korea. 2. Temperatures in soil 20cm deep during the period from late part of March to middle part of April had high correlations with budding dates. 3. It was disclosed that the budding date had high correlations with the date of bud shaped swallow-bill (r=0.9861**), date of the first leaf (r=0.9861**), date of the third leaf (r=0.97**) , and date of the fifth leaf (r=0.96**), respectively. 4. The higher the average temperature of April became, the longer the length of shoots became. 5. The earlier the budding date and foliating date came, the larger the leaf yield became. However, with excessive amount of precipitation after early budding and foliating, the leaf yield was not increased in proportional. 6. The longer the growing period of the shoots became, the larger the leaf yield became.

Ideal candidates for the thermal-protection system of advanced spacecraft like Space Shuttle, are FRCI(Fibrous Refractory Composite Insulation) and AETB(Alumina-Enhanced Thermal Barrier). In the present work, we carried out the mathematical modeling and computer simulation of the thermal response of FRCI to heat, pulse, comparing with that of silica. Also, we calculated the conductivity of FRCI as various variables at the temperature range of 100~2000 K. 우주왕복선과 같은 발전된 비행체의 열 차단 시스템(TPS)에서의 이상적인 후보로는 섬유질 내화성 복합 절연체(FRCI)와 AETB(Alumina-Enhanced Thermal Barrier)가 있다. 이중, 본 연구에서는 FRCI의 열 펄스에 대한 열적응답을 실리카와 비교하여 수학적으로 모델링하여 전사모사 하였다. 또, 100~2000 K의 온도범위에서 FRCI의 여러 변수에 따른 각 열전도도를 계산하여 보았다.
